Add an auxiliary Voltage to a Buck regulator - 10/31/02 EDN-Design Ideas: You
often need more than one regulated output voltage in a system. A frequently used and
reasonably simple way to create this auxiliary output voltage is to add a second
winding to output inductor, creating a coupled inductor or a transformer,
followed by a diode to rectify (peak-detect)this output voltage.....(design idea added

Boost Converter works with Wide Range Negative Input Supply - 03/18/04 EDN-Design
Ideas: Assume that a design requires positive voltage, but only a negative-voltage
power source is available. Using a standard boost-converter IC in circuit of
Figure 1, you can efficiently generate a positive voltage from a negative source. The
boost converter generates an output voltage that's higher than input
voltage.....(design idea added 1/05) |

Buck Boost Regulator Suits Battery Operation - 09/04/03 EDN-Design Ideas: A
buck/boost converter can step a voltage up or down. Such a converter is appropriate
for battery-powered applications. One application derives a regulated 14.1V at 1A from
12V solar panels with 9 to 18V variation. In this type of battery application,
efficiency is an important factor; hence, this design uses an inexpensive
synchronous-rectifier-based MC33166/7 circuit.....(design idea added 1/05) |

Buck converter charger also provides system power - 05/22/97 EDN-Design Ideas:
-Switching Regulator provides charge voltage setpoint with Current regulation,
and second Switching Regulator provides5V System Power -Many systems require long-time
operation during periods of power loss. Often, a gel or wet-cell lead-acid battery is
best choice because of high capacity and relatively low cost.....(design idea added

Buck/Boost Reference Design - This reference design presents an alternative to
typical boost power regulator. A buck converter IC is used to generate a higher
voltage needed by white light LED power from a Ni-Cd battery. This circuit
operates by turning high switch on, connecting battery voltage across
inductor. Once sufficient energy is stored in inductor, ..... (added 3/05) |
